Abstract (en)
[origin: EP0406784A2] The device comprises a first section (25) , which comprises logic circuit means which generate the law of motion along the machine operative trajectory arc, and a second section with a set of three digital polynomial generators (27-28-29), each of which receives from the motion law generator means the instantaneous value of the curvilinear coordinate and, from an external processing unit, the polynomial coefficients related to the trajectory arc to be generated and the sampling and sub-sampling pulses; the polynomial generators of the second section are suitable for providing, on the respective outputs, the corresponding components of the instantaneous speed vectors of each point of the trajectory, generated by adding and multiplying the polynomial coefficients and the curvilinear coordinate.
